IMPROVED BRIGK MAEINE.

To WHoM 1T MAY coNoERN': t

Be it known that I, Gronau C. Bovine-of Cincinnati, Hamilton; county, Ohio, hiive invented 'a nevmnd `usefulBriekl Machine; and I hereby` declare the followingto hearfull, clenijandfexnct description thereof, reference being had to the accompanying drawin'gmvmaiking part of this speciicotion. l

The third part of my improvement consists in a. device for punctringthe bricksV with series of `forks for i of squering the faces of lche bricks, operoted by afsprrng und piniomfos shown the i-darwngf ihSQPl?. i ation the surplus clay is `pressed into the centro of the mouldLiiisteod of .being `cut or scraped oii`, a s in other ^mechines.

My fifth improvement consists in a hollow plunger, with-a. forkoperatinginf'tliefcentre. My sixth improvement consists in a grooved cam for' opeg Figure 1 is an end elevation of` a brick machine embodying `mjy improvements, a.` portion of rthefreine-being broken away so asz'to exhibitone ofthe 1nou1d-wheels end its sccompenyingcomytc.

The clay is Ipressed into the moulds or 'chamhers of the mould-wheels by the following devices: J J nre two feed-rollersor wii, llovvers`,`'located in thehopperK,

and each of these is provided with `longitudinal` corrugations jj@ and :is the-peripheriesof'these two rollers are in contet with earch other the cavities or corrugutions j j serverto drow the clay` down from the ,hopperend force it into the moulds, It will be seen that this arrangementinsuresthe com-plete filling ofhth'emoulds, sind, in ease the feed-rollers should draw too much cloy towards the `mol-'11de the corrugntion's will permit .the

return of the over-plus hack to thohopper K, and thus save the machine `from any injurious stioin-V lcihliged'.4 to

My invention is :in improvement inmechines ivhi hereomployed for makin bricks from-dry c loy oi' tem'- nevof the 'plungers and its lccompanying device for the purposejof `perthe sides of the frame of 4the machine are plates 7c, which t vbetween the mould-wheels B C, ,andl tho's'fe plates are provided with suitable stays to keep `them in their` places, thereby Apreventing the mud ,from running out. Lis a division tongue,- whieh retains thc'mud in the moulds until .the bricks are completely formed all but facing, which is donc by the iiatlface rollers M M', and these rollers4 are journalled in boxes m, having springs m' forkeeping the roller 'in contact with the mould-wheel, andyet allowing the facing-wheel or roller to operate on the face of the brick andisquvare it whilejt is in the' mould. N N' are endless carriers, which convey. the newly-formed bricks away from the machine; and these carriers' may be of any'v length, and it' the bricks -l are not pressed dry when they come from the machin-@said carrier` could be 'made to pass the bricks through e. hot furnaee,-on the way to the kiln,- thereby drying them so that they could be put in thckiln as` they come from the machine. The grooved cam-plate F f is provided with a hub, O, and the shafts band e of thel mouldwheels revolvewith-in the hub, while a flange, O, projecting 'from the cam-plate F, and being bolted to one-oi` the post-sa a' prevents the rotation of said cam. One side of the cam is dished so as to admit oi' its revolving around the hub P ofthe mould-wheel, as is shown in fig.` 3.- Power is' communicated from the engine to the machinein tho-following manner 'Pis the driving-shaft, having a pulley, R, and pinion,`^f, the pulley -R being rotated by a belt, S, from the engine, whilst the pinion i' gears with the spul-wheel T of `the mould-wheel B, and said wheel T meshes into another spur-wheel,I T', vof corresponding size, which is attached to the shaft c of the other mould-wheel C. The pinion Ir-xnay be omitted and a worm substitutedl'for it, that is, ,if the pinion is not sufficient to run the machine when at work, and also the flat-faced roller'can be changed, in constructing@ a machine, and placed in the tongue L. The pressure-rollers MM' have pinions u u', which gear with the spur-l p wheels T T', and the corrugated feed-roller J' xsprovided with a pinion, L', which is rotated from thewheelT by the intermediate wheel U'. The feed-roller J' imparts a corresponding rotation to vthe other roller Jby the even-geared cog-wheels V V'. The drums W W' of the endless carriers N N' may he driven either by pinions n geared with the spur-wheels T T' or else by a belt.

p The operation of my .machine is clearly exhibited in fig. 2, and `it will be seen that the clay is 'forced into the moulds E as fast as the rotation of the mould-Wheels B C brings the open ends of saidmoulds within the hopper K, and the clay is continually packed intofthesmoulds by the rollers J J', ,and is pressed into bricks the two mould-wheels pressing together, the solid metal of one pressing'the clay in thc'other. As soon as the v moulds arrive at the top of the dividing'tong'ue L theswell 1 of 'the.eccentric-groove f'icauses the puncturing points i. 71. to'protrudcfrom the'hollow plunger and enter the bottom of the brick, and asthe mould-wheel' revolves the eccentric portion of the cam F f, which extends from 2 to 3, imparts a gradual simultaneous advaneement of the plunger D and points t, thus compressing the bricks thoroughly', and; to their proper thickness. After the moulds have passend'thetongue o r plate L,`the hexagonal pressure-roller M imparts the square vface to the brick. When the mouldsk have arrived directly under the shafts I or c of the` wheel, the enlargement 4 of the cam forces the bricks from the moulds on to thcendless carriers N N', and after passing this swell ,the

points i t'h" are retracted by the'spring I. The opening` made in the under side of the bricksby the points L L"L" are for the purpose' of allowing" the steam and dampncss to escape from tho centre of. the brick'whilst I drying or burning, and for the mortar to eht'crwhen the bricks are laid in the wall, thereby; acting as dwels, and making the bricks more firm when the mortar is dry. In order to increase the capacity of the maehi-nc itg may be double,that is, having 'two wheels on each shaft, thereby making double the number of bricks laty each revolution of vthe mould-wheel; each wheel to be provided with its own vfixed cani-plate and carrier. n

I claim herein .as new, and of my invention-'- y 1. The provi-sion in a brick machine of the two .feeding-rollers. J J', having longitudinal corrugations jj', geared together to turn in the same direction as the respective mould-ivl1cels, and so as not to mesh into cach' other, and operating substantially as shown.

A 2. I also claim the puncturing points h h' It", operating within a hollow plu-nger and operated by' a groei-'ed'` stationary cam, in combination with the pressing devices, as shown and described.

` `3. I claim the solid parts .of the mould-wheels pressing the bricks, las shown in the drawings, also the mouldwheel when arranged with stationary grooved cam, hollow plungcrs, grooved friction-rollers, with puncturer operating or sliding through it', with shaft of mould-wheel passing through the cam, all arranged and operating` n the manner described. 1 v

4. I claim the dividing tongue L, when placed between themould-wheels Band C, and when used for the purpose described. i 5. In combination with themould-wheel B I also claim the hexagonal or other square-faced pressure-roller, when made and used in lthe manner described and for the purposes set forth, orany other polygonal springroller, for the purpose of squaring the faces of the brick without sera/ping or cutting the clay or the face of the brick.

6. I also claim the combination of the mould-wheels B C, feed-rollers J J', dividing tongue L, pressurerollers M M', and aprons N N', when made and used substantially as shown and' described."

In testimony of which invention I hereunto set my hand. l
